Username Font Styles

I just want to know how to change the Font styles of the Usernames.

E.G: Admins: Font Style: Bold, Font Color: Black

Create a user group {must be a colored group,and has the ability to color members usernames}.

And add the member to the group.

To create a group:
ACP=>Users & Groups Tab=>Groups=>Group Administration=>Create new group=>After filling in the info,check add these fileds must be done:

~Group Members Color - Choose color
~Color Group Members - tick yes

=>Save

To add the member to the group:
When the group is colored,you'll see it in your legend on your forum.Click the group,and you'll see a box at the bottom,type in the member's username,and press Add member.

Thank You. Helped alot

Your welcome.
